Whitney Heichel: Police Search Wooded Area for Missing Oregon Woman

Authorities used red tape to mark where they found broken glass and tire marks in a heavily wooded area in Gresham, Ore., as part of their search for a Starbucks employee who disappeared on her way to work.

It's unclear whether they found any significant clues.

Investigators searched the park in Clackamas County and also Larch Mountain Wednesday in connection to the disappearance of Whitney Heichel, 21. She was last seen Tuesday when she kissed her husband goodbye and left for work at Starbucks, a five-minute drive from her home.

Gresham police have called Heichel's disappearance "suspicious" and fear they are in a race against time to find her.

"Right now we have 24 detectives working on it," Gresham Police Department spokesman Lt. Claudio Grandjean said. "We want to be able to jump on leads we have right away. The colder those leads get, the more difficult it becomes."

Of the park findings, he said, "I'm not prepared to say that's the broken glass that came from her vehicle, although it's absolutely possible."

Heichel's black Ford Explorer was found abandoned in a Walmart parking lot hours after her disappearance. The passenger side window had been shattered.

Police aren't saying what brought them to search the wooded area.

Heichel's husband, Clint, has said she kissed him goodbye and left for her job just before 7 a.m.
